THM –TUNNEL FREEZER - IQF – HELICAL (SPIRAL)
Two retention times in a single device
Product description:
The helical freezing or cooling tunnel is designed to meet specific characteristics of each product. Ideal for freezing or cooling cuts of chicken or fish, bread, burgers, processed foods, frozen meals, pizza, fruit and vegetables.
THM WITH DIRECT TRACTION ON THE CONVEYOR is an IQF (Individual Quick Freezing) tunnel freezer, which uses the most advanced and latest direct drive technology for the belt.
Conventional Spiral Freezers operate through a friction drive belt; the drum rotates in its inner radius and the tension of the belt is controlled by a second drive - “take-up”.
The ratio of the speed of the belt and the speed of the drum avoids that the belt is either too tight or too loose - “overdrive”. This ratio varies according to the friction between the belt and the drum and between the belt and its supports.
The wear of the supports, product fragments that are deposited on the conveyor belt during production, changes in the weight and quantity of the product to be frozen, among other factors, alter the friction coefficient and require constant attention from the operator when adjusting the overdrive.
